一种基于STV控制的分区栅极扫描方法及显示面板A partitioned gate scanning method based on STV control and a display panel

技术领域technical field

本发明涉及显示面板技术领域，特别涉及一种基于STV控制的分区栅极扫描方法及显示面板。The invention relates to the technical field of display panels, in particular to a method for scanning partitioned gates based on STV control and a display panel.

背景技术Background technique

触摸显示一体化是指将触摸感测电极直接集成在显示面板内，有效降低面板厚度、降低成本。如在日本专利(日本特开2012-59265号公报)中，公开了使内嵌式的触摸传感器和显示元件分时地交替动作的显示装置及其驱动方法。分时地交替地进行触摸传感器的传感和显示元件的驱动，即触控与显示驱动集成(Touch and Display DriverIntegration，TDDI)IC。这是将一帧分割为显示模式和触摸传感模式并通过定时控制器(timing controller)来控制栅极驱动器、源极驱动器、以及触摸控制器从而交替地执行这两个模式的方式。在该系统中，针对每多行间歇地进行图像显示，在来自显示驱动器的图像输出停止的期间进行触摸感应，由此实现了高触摸检测精度。The integration of touch and display means that the touch sensing electrodes are directly integrated into the display panel, which effectively reduces the thickness of the panel and reduces the cost. For example, Japanese Patent Application Laid-Open No. 2012-59265 discloses a display device in which an embedded touch sensor and a display element are time-divisionally and alternately operated, and a driving method thereof. The sensing of the touch sensor and the driving of the display element are performed alternately in a time-division manner, that is, a touch and display driver integration (Touch and Display Driver Integration, TDDI) IC. This is a way of dividing one frame into a display mode and a touch sensing mode and controlling a gate driver, a source driver, and a touch controller through a timing controller to alternately perform the two modes. In this system, image display is intermittently performed for every plurality of lines, and touch sensing is performed while the image output from the display driver is stopped, whereby high touch detection accuracy is realized.

TDDI类显示面板将显示和触控分时驱动，可以增强触控和显示集成于一体的效果，但是该驱动方式经常会出现显示横纹，影响显示效果。The TDDI type display panel drives the display and touch in a time-sharing manner, which can enhance the integration effect of touch and display. However, this driving method often causes horizontal stripes on the display, which affects the display effect.

产生横纹的问题主要由于在某个时刻，VCOM块上面的栅极驱动线对该VCOM块的耦合作用。The problem of horizontal stripes is mainly due to the coupling effect of the gate drive line on the VCOM block to the VCOM block at a certain moment.
